[QUOTE="carl beasley, post: 643405, member: 54280"] I posted here before describing the whine coming from the rear of my Trac. 2001ST, mileage just over 72K miles. I've replaced the tires, shocks, wheel bearings and rear brakes. Still have a whine that starts at 25mph and increases in pitch the faster I go. If I let off the gas, the whine quits. No difference in the whine pitch while cornering. Just while under acceleration and at cruise. Let off the gas = no noise. So, pinion bearing &/or pinion gear. Ford Dealer says 1K to 1.5K to rebuild. Local Goodyear shop is in the same ballpark. Questions: Any info on new rear axle suppliers? I have a 3.73 axle. What if I drop in a 4.10? Any problems with tranny, speed-o ? Any other suggestions? thanks, Carl [/QUOTE]
